Summary of discussion:

Key points/Issues raised & Solutions

• What if some programs have some features but others don’t.
  • disable the buttons or make information removed
  • do not blindly trust what is promised to be provided by the spec
• Broadcasters data is limited
• Make AI aware what is going on the screen
  • More data needs to be provided
• Synopsis availability is variable
  • Depending on the length, it can be used for each use case accordingly such as channel list, Program details, recommendation
• Additional meta-data from broadcasters needs a business model

• • Through participation in a minimum data set, all broadcasters can benefit from its existence.
  • Voice and AI search requires good meta-data to work and offerings will get better prominence in search when they have rich meta-data.

• Logo issues: Some dark channel logos is barely visible on dark UI

• • Use Image Variants in DVB-I Specification, which allows the clients to get both of dark and light color of channel logo.

• Delivery type issue

• • HLS is other type – requires a work around – weird confused developers
  • Multiple delivery – if how do I choose which one

• • • There is a priority but it is optional – normally is used
  • Recommended to have different priority.

• New end points

• • End point for semantic search
  • End point for recommendation

• • • Multiple type of recommendation

• • • • Promotions
      • Segmented profile recommendation
      • Personalised recommendation based on activity

• • • What is the key, backend has to keep a record
    • Recommendation can be based on the current viewed item
    • Could recommendation be stored in the client

• • End point for like and share
    • From DVB-I Client side, it can count the number of like and share. The recommendation logic can be created using those numbers.

• Meta-data in DASH event stream
  • From DVB-I Client side, Meta-data in DASH stream can be used for rich UX.

Next steps:



Broadcasters need to provided as much metadata as possible. This would attract users to view their channels and content.
DVB-I Client implementers can use Image Variants in DVB-I Spec to show channel logo clearly on any of dark or bright UI.
Recommendation would be useful for more viewers but still metadata will be required to have recommendation logic.
